Six Precision Validation Systems
Every critical interconnect parameter is validated on calibrated in-house equipment — sealing, mechanical, thermal, corrosion, dielectric and dimensional performance.
IP67 / IP68 / IP6K9K Air Leakage & Waterproof Tester
Air pressure decay & high-pressure water sealing
Quantitative leak-rate testing on sealed connectors to verify IP67 / IP68 / IP6K9K ingress protection under pressure and jet-spray conditions.
Automatic Terminal Insertion & Extraction Force Tester
USCAR-21 / LV214 insertion & pull-out force testing
Automated insertion and extraction force measurement to validate terminal retention against USCAR-21 and LV214 automotive specifications.
Thermal Shock & Environmental Aging Chamber
-50°C to +150°C thermal shock testing
Rapid high-low temperature cycling and environmental aging to verify material stability and contact reliability under severe thermal load.
Salt Spray Corrosion & Contact Resistance Tester
96h ~ 240h salt spray & micro-resistance analysis
Long-duration salt spray corrosion exposure combined with low-resistance micro-ohm analysis of plated terminals and contacts.
High-Voltage Dielectric & Insulation Resistance Tester
AC 1000V / 1500V dielectric withstand testing
AC dielectric withstand and insulation resistance testing to confirm electrical isolation integrity across connector assemblies.
Optical Video Measuring System (VMS / CMM)
Non-contact 2D / 3D micron-level measurement
Non-contact optical and coordinate measurement for micron-level dimensional verification of housings, terminals and tooling.
Authority-Approved Quality System
Our manufacturing and quality management systems are certified to global automotive and environmental standards, with full documentation support for OEM programs.
